Another great book is "Sword of the Spirit...the Word of God" by Joy Lamb. It had been out of print, but I see Amazon has it back. http://www.amazon.com/Sword-Spirit-W.../dp/0970554605
Anyone who is being bothered by spirits needs this book, great deliverence prayers, prayers for breaking curses and for renouncing the occult. This is technically not a Catholic book, but the prayers you can find on most Catholic websites on deliverence.
